![]() The SequenceDiagram solution contains two projects: SequenceDiagramLib has the actual control whereas the SequenceDiagramTestApp project has various examples demonstrating the capabilities of the control.Īll but one of the samples run entirely in the main thread. That is, dynamic analysis is performed on a running system, whereas static analysis is performed on system artifacts (e.g., source code). ![]() Dynamic analysis differs from static analysis is that it requires an active system to model. This activity may be the live method calls in a computer program, the communication within the components of a distributed application and so on. ![]() They behave as blueprints of a process and serve for communicating the interaction within the system.īut sequence diagrams can also be used for visualizing real-time activity of a system. Most existing use of sequence diagrams is limited to static models: The diagram is based to a definition of a model, or a static code. This, in turn, enables sequence diagrams to show “what happens” in the system. As a result, the concept of time, as well as dependencies between objects, appears in sequence diagrams. Sequence diagrams show the behavior of objects. Near the end of the article, I provide a proof of concept for this type of usage. NET application by using AOP (Aspect Oriented Programming) techniques, and now you want to visualize the captured call trace as a process graph: You have developed a software tool that intercepts method calls of any. The control has originally been created for this scenario, and forms a part of it. You forward the log events of every microservice to a collector, so that you can visualize the entire flow in a single sequence diagram for easier analysis and debugging: You have a distributed application composed of separate components (such as microservices) residing on different computers, and you have difficulty tracing the entire execution. Here are two scenarios in which the control would be of use: End-To-End Tracing of a Distributed System In addition, it provides a practical-use sample in which an application's execution is intercepted and visualized in real time. The control incorporates break functionality similar to a debugger's. NET control for dynamic visualization of objects and their interactions as sequence diagrams. Their clear graphical layout helps give a quick intuitive understanding of the system’s behavior. They allow describing interactions between the system and the actors of its environment or between the participants of the system over time. Their focus is in modelling the dynamics of a system. Sequence diagrams are one of the fundamental types of UML diagrams.
